IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND PROGRAM, AND IMAGE PICKUP APPARATUS INCLUDING IMAGE PROCESSING APPARATUS

摘要

The image processing apparatus processes an image signal obtained from an image pickup element, using an image pickup optical system arranged to obtain directional traveling information of object image light corresponding to a pupil division area of a photographing lens. The apparatus includes: a unit of setting a focal position at which the refocused image is generated; and a unit of correcting an image signal of a defect pixel of the image pickup element using an image signal of other pixel. The apparatus determines the other pixel to be used for correcting the image signal of the defect pixel on the basis of the set focal position and the directional traveling information of the object image light.

主权项

1. An image processing apparatus for processing an image signal obtained from an image pickup element using an image pickup optical system arranged to obtain directional traveling information of object image light corresponding to a pupil division area of a photographing lens, comprising:
a synthetic image plane position setting unit configured to set a position of a synthetic image plane on which an image of the object is reconstructed using the image signal obtained from the image pickup element; and a correction unit configured to correct an image signal of a defect pixel of the image pickup element using an image signal of another pixel of the image pickup element, wherein the correction unit determines the another pixel to be used for correcting the image signal of the defect pixel on the basis of a position of the synthetic image plane set by the synthetic image plane position setting unit, and directional traveling information of the object image light.
